1.4 Applied motor (Pr. 71)
(1) Set the motor to be used
Refer to the following list and set this parameter according to the motor used.
Setting of the used motor selects the thermal characteristic appropriate for the motor.
Setting is necessary when using a constant-torque motor. Thermal characteristic of the electronic
thermal relay function suitable for the motor is set.
When PM sensorless vector control is selected, the motor constants (MM-CF etc.) necessary for control
are selected as well.
